We now have three hypervisors working on a Hardware with H extension. 1. KVM [1] 2. Xvisor [2] 3. Bao [3] KVM bring up was done using Firesim and the detailed instructions will be available very soon. Here are the software versions used for bringup. Please find the attached boot log. OpenSBI: v0.9 Linux kernel: 5.11-rc5 + KVM patches(v16) + few kernel fixes [4]. Kvmtool: Upstream + RISC-V KVMTOOL patches (v6) [5] We would like to thank Sandro & Jose who implemented the H extension. The Rocket-H design is available as a AFI image to be used within Firesim or a stand alone FPGA board. We would also like to thank Andrew/John/Greg & others for defining such a clean specification as we did not discover any significant issues while doing the bring up. As there are no changes proposed to the H extension in the last year, we believe the current version of the H extension can be considered as a freeze candidate. Please let us know if that is not the case. -- Regards, Atish [1] https://github.com/kvm-riscv/howto/wiki [2] https://github.com/xvisor/xvisor [3] https://github.com/sandro2pinto/bao-rocket-h-firesim [4] https://github.com/atishp04/linux/commits/rocket_kvm_working [5] https://github.com/kvm-riscv/kvmtool <kvm_fpga_boot_log.txt> -- Regards, Atish

Sean Halle #512 Thank you for sending out the announcement, and congratulations :-) I was wondering about the Rocket-H RTL. Did some searching, which didn't turn up much. Is that in the rocket-chip repo? If not, is it open source? If so, I would really appreciate a pointer to the implementation. Thanks, Sean toggle quoted message Show quoted text On Tue, Feb 2, 2021 at 11:18 AM Atish Patra <atish.patra@...> wrote: On Tue, 2021-02-02 at 03:14 -0800, mark wrote: > congrats! > > can we send something out to tech-announce about it? > Sure.

Sandro Pinto #513 Hi Sean, The rocket-chip repo with our H-extension (a.k.a. Rocket-H) implementation can be found here: https://github.com/josecm/rocket-chip/tree/hyp Here you can find instructions on how to build and run the Rocket-H on FireSim with our hypervisor (Bao): https://github.com/sandro2pinto/bao-rocket-h-firesim Feel free to ping us if you have any doubt or question..
